Martindale Abrasion and Pilling Tester T331 is a widely used testing instrument in the textile industry for assessing the wear resistance and pilling characteristics of fabrics. It simulates everyday wear and tear by rubbing fabric samples against standard abrasive surfaces or other fabric samples under controlled pressure. This tester is essential for determining the durability and appearance retention of fabrics used in garments, upholstery, automotive interiors, and other textile products.
